Centre-fed microstrip patch antenna
Jireček, Martin ; Láčík, Jaroslav (referee) ; Raida, Zbyněk (advisor)
Systems with extreme bandwidth are part of advanced modern systems at radio high capacitive communication. Originally this technology was intended for radar scan. Thanks to wide frequency band had radar possibility „ see" a behind crimp, e.g. behind woody partitions etc . To his noise immunity, fail safe tapping plus small wattage heftiness began use for datal systŽm function. If is elementary antenna compound from coaxial probe and shorting outlet, it is possible use to actuating separate narrow slot placed in the middle of incandescent dabs. Impedance and radiating characteristics conventionally plumbed phlobaphene antennae excited tape lead and suggested microstrip phlobaphene antennae are experimentally explored plus collated. Explored is so and effect changes slotted longitude slot on characteristics elementary antenna.

Circularly polarized SIW cavity-backed microstrip patch antenna
Procházka, Petr ; Láčík, Jaroslav (referee) ; Mikulášek, Tomáš (advisor)
This bachelor thesis deals with a circularly-polarized substrate-integrated-waveguide cavity-backed microstrip patch antenna. The first part dedicates basic theoretical knowledge of microstrip patch antennas such as patch shape, the possibility of its excitation etc. The following part describes the possibilities and adjustments of generating circularly-polarized wave from a microstrip patch antenna for generating circularly-polarized waves and general knowledge about the advantages and application of circularly-polarized wave. The next part deals with a step-by-step design of a proposed antenna. The last part present a comparison of simulated and measured results.
